The ability to store an electric charge. Capacitance is measured in farads. A capacitance of 1 farad will hold 1 coulomb of charge at a potential of 1 volt. In practical use, a farad is an extremely large amount of capacitance; typical capacitors have values of microfarads (10-6 ) or picofarads (10-12 ). See also capacitor.
An electrical phenomenon whereby an electric charge is stored; SYN. electrical capacity, capacity.
Electricity, ability to store an electric charge; measure of such ability.
